How much energy is transferred when 30.0 g of water is cooled from 25.0⁰C to 12⁰C

What is the number of moles in 15.0 g ash3?

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that

Label a-f based on the table using c for concentrated and d for dilute
